Hanyoyi na al'ada don ajiyan sutura masu wuya

1. Thermal CVD fasaha

Hard coatings yawanci karfe yumbu coatings (TiN, da dai sauransu), wanda aka samu ta hanyar dauki karfe a cikin shafi da amsa gasification. Da farko, an yi amfani da fasahar CVD ta thermal don samar da kuzarin kunnawa na Haɗuwa ta hanyar makamashin thermal a babban zafin jiki na 1000 ℃. Wannan zafin jiki ya dace ne kawai don ajiye TiN da sauran sutura masu wuya akan kayan aikin carbide da aka yi da siminti. Ya zuwa yanzu, har yanzu yana da mahimmancin fasaha don saka TiN - Al2O3 kayan haɗin gwal akan kawunan kayan aikin carbide da aka yi da siminti.

1. M cathode ion shafi da zafi waya arc ion shafi

A cikin 1980s, an yi amfani da murfin cathode ion mai zurfi da murfin ion arc ion mai zafi don adana kayan aikin yankan. Duka waɗannan fasahohin suturar ion sune fasahohin fitarwa na ion, tare da ƙimar ionization na ƙarfe har zuwa 20% ~ 40%.

1. Cathode arc ion shafi

Bayyanar cathodic arc ion cating ya haifar da haɓakar fasahar adana kayan kwalliya mai wuya a kan molds. A ionization kudi na cathodic arc ion shafi ne 60% ~ 90%, kyale babban adadin karfe ions da dauki gas ions isa surface na workpiece da kuma har yanzu kula da high aiki, sakamakon a dauki jita-jita da samuwar m coatings kamar TiN. A halin yanzu, ana amfani da fasahar shafa na cathodic arc ion don saka riguna masu wuya akan ƙira.

Tushen katode baka shine tushen ƙawancen yanayi mai ƙarfi ba tare da kafaffen tafki na narkakkar ba, kuma ana iya sanya matsayin tushen baka ba bisa ka'ida ba, inganta ƙimar amfani da sararin samaniya na ɗakin rufi da haɓaka ƙarfin wutar lantarki. Siffofin maɓuɓɓugan baka na cathode sun haɗa da ƙananan madauwari na cathode arc, tushen baka na columnar, da manyan maɓuɓɓugan baka na rectangular. Za a iya shirya sassa daban-daban na ƙananan maɓuɓɓugar baka, tushen baka na columnar, da manyan maɓuɓɓugan baka daban don saka fina-finai masu yawa da fina-finai na nano multilayer. A halin yanzu, saboda da babban karfe ionization kudi na cathodic arc ion shafi, karfe ions iya sha mafi dauki gases, sakamakon da fadi da tsari kewayon da sauki aiki don samun m m coatings. Duk da haka, akwai ƙananan ɗigon ruwa a cikin ƙananan tsarin rufin da aka samu ta hanyar cathodic arc ion. A cikin 'yan shekarun nan, yawancin sababbin fasahohi sun fito don tsaftace tsarin tsarin fim din, wanda ya inganta ingancin fim din arc ion.
